Plexiform neurofibroma is a rare, poorly defined benign tumor of the peripheral nerve sheath. It spreads out just under the skin, or deeper in the body, and occurs exclusively in patients with neurofibromatosis type I. Facial plexiform neurofibroma may produce various degrees of cosmetic and functional deformities in the head and neck region. It is a virtually pathognomonic and often disabling ...

Neurofibroma is a slow growing benign tumour of the peripheral nerve sheath which is frequently associated with neurofibromatosis type 1 (Prakash et al., 2014). Isolated solitary occurrence of neurofibroma in the maxillary sinus is rare with only 29 reported cases in the literature. We present a rare case of a 70-year-old gentleman who was referred to ENT with a right maxillary sinus neurofibro...

Deregulation of RAS signaling in Neurofibromatosis type 1 (NF1) results in the development of multiple neurofibromas, complex tumor of the peripheral nerves with no effective medical treatment. There is increasing evidences that neurofibroma initiates through loss of NF1 function in the Schwann cell lineage, followed by a cascade of interactions with other cell types in the surrounding tumor mi...

Gastrointestinal neurofibroma usually develops as diffuse gastrointestinal involvement in neurofibromatosis type 1 patients. Only 4 cases of sporadic colonic neurofibroma in a patient without neurofibromatosis type 1 have been reported in the English literature. A 26-year-old female patient underwent colonoscopy, and a 4-cm-sized polypoid mass was identified in the sigmoid colon. Wedge resectio...

BACKGROUND Neurofibroma of the male breast outside of neurofibromatosis is extremely rare with only one previous case having been reported. CASE PRESENTATION A 48 year old male patient with a neurofibroma in the breast presenting with gynaecomastia is reported. Clinical and mammogram findings with fine needle aspiration cytology and full histology are presented. CONCLUSION To our knowledge ...

Intramedullary spinal neurofibroma is extremely rare. A case of cervical intramedullary neurofibroma is presented in a 21-year-old man. Only 20 case have been previously reported in the literature. The site of origin is discussed with various hypotheses.

We present a case of subglottic neurofibroma, which is of interest because laryngeal neurofibroma rarely occurs in the subglottic space. Nonspecific MR findings did not allow us to exclude the preoperative diagnosis of hemangioma.

Facial nerve neurofibromas are an uncommon entity, particularly in the intraparotid region. Three cases are presented herein, including the first reported case of both an intratemporal and intraparotid facial nerve malignant neurofibroma. To the best of our knowledge, this is the first medical publication to describe a neurofibroma involving both the intratemporal and intraparotid regions. The ...

The peripheral nerve sheath tumours can be separated into benign and malignant types. Schwanomma, neurofibroma and perineurioma are benign tumours. Neurofibromas are rare in Head & Neck region, but are most common among neural lesion in the region [1]. Up to 10% of these lesions are associated with Neurofibromatosis, an autosomal dominant disorder. Neurofibroma can be of three subtypeslocalised...
